American Lung Association Ranks Cleanest And Most Polluted U.S. Cities

The American Lung Association released a report ranking the cleanest and most polluted U.S. cities, a summary shared on CBS News' Facebook page. The report compares fine particle and ozone levels across metropolitan areas to highlight where breathing risks are highest and lowest. The Facebook post linked to the findings for wider public discussion and reaction.

Air quality rankings like this often shape local public health alerts, transportation planning and clean-air policy priorities. They also prompt social media debate about urban growth, industry emissions and wildfires, which can sway public opinion and political attention. The CBS Facebook post did not include detailed city-by-city statistics, so readers should consult the full American Lung Association report for specifics.
